NATURAL-GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 427,299, dated May 6,1890. Application filed August 16, 1889- Serial No. 321,030. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES H. CARPEN- TER, a citizen of the UnitedStates of America,

- residing at Richmond, in the county of WVayne and State of Indiana,have invented certain new and useful Improvements in Natural- GasBurners of which the following is a specification, reference being hadtherein to the accompanying drawings.

My invention relates to that class of burners used in the economicalcombustion of natural gas for domestic purposes, and more especially toburners having in each instance a cap which is set into a channel formedon the upper face of a tray-bottom part or base.

The said invention consists in the improved construction and combinationof parts, hereinafter set forth and claimed.

In the drawings, Figure 1 is a top view of the burner, showing theperforations for the escape of the gas and the projecting edge of thetray or bottom part of the burner. Fig. 2 is a side elevation of thesame. Fig. 3 isa top plan view of the upper surface of the tray orbottom part of the burner, showing the inlet-pipe and thedeflecting-plate and the recess or channel around its outer edge. Fig.4. is a vertical longitudinal section of the tray or bottom. Fig. 5 isan end elevation of the burner. Fig. 6 is a vertical cross-section.

In Fig. 1 A represents the tray or bottom part of the burner, which isin the form of a rectangular plate, having its outside edge flanged atright angles, forming a rim projecting upward from the horizontal planeof the bottom plate. Immediately inside of the rim there is placed a ribor bar corresponding in form with the outside rim, which is raised tonearly the same height as said rim, as seen in Fig. 6 at L, the raisedrim and rib thus forming a channel or recess into which the verticalsides and ends of the cap or cover fit loosely, as seen in Fig. 6. Thetop surface of the cap or cover is studded with rectangular projectionsraised vertically from the surface marked 11 i 2 412', which givestrength and radiating-surface to the cap, and it is also provided withnumerous perforations n n n n 'n for the escape of gas in the process ofcombustion. An ornamental plate It occupies the central position on thetop surface of the cap or cover B.

In Fig. 2 1) represents the inlet-pipe by which the gas is admitted tothe burner. A inFig. 3 represents a deflector-plate placed vertically atright angles to the longitudinal plane of the burner near to andopposite the inlet-pipe and serves to spread the current of gas as it isadmitted to the interior of the burner and distribute it more evenlythroughout the gas-chamber. The upper surface of the cap or cover B isdivided into three longitudinal sections by the lines 0000, each ofwhich sections has a curved surface flattened medially, as shown at m mm, Figs. 5 and 6. These convolutions serve to in a measure equalize theexpansion and contraction of the cap or cover B and to prevent crackingor breaking. The recess or channel 0 e c eis to be filled with sand orother suitable substance to form a packing which is self-acting, andprevents the escape of the gas between the top and bottom parts of theburner. It will be seen that I thus construct a burner composed of twoparts which requires no bolts, clasp, allows of the expansion or thecontraction of either part without strain upon the other.

Having thus fully described my said improvement, what I claim as new,and desire to secure by Letters Patent, is

In a gas-burner, the combination, with a base having a flange, asupplemental inner ridge, the inlet-pipe, and a gas-deflector, all castin one, of a perforated longitudinallyridged cap B, fitting in thechannel formed by said outer sides and inner ridge, and projections z',strengthening said cap-B, substantially as set forth.

In testimony whereof I Et'ffiX my signature in presence of twowitnesses.

CHARLES H. CARPENTER.
